Hiiii

Thanks for the reply...i really appreciate that....

The "netstat -altpn" command does not show any process or application listing to 5060 other than kamailio !

Also after using the "ps -aux | grep kamailio" i see only kamailio is running as single process and does not do process forking as below

[root@Kamailio kamailio]# ps -aux | grep kamailio
Warning: bad syntax, perhaps a bogus '-'? See /usr/share/doc/procps-3.2.8/FAQ
root 4163 0.0 0.2 156916 2608 ? S 09:00 0:00 /usr/local/sbin/kamailio -P /var/run/kamailio.pid -m 32 -M 4 -u root -g kamailio
root 4245 0.0 0.0 103248 836 pts/1 S+ 09:02 0:00 grep kamailio

Also here is some logs tail /var/log/messages | less

Nov 3 09:00:55 Kamailio /usr/local/sbin/kamailio[4162]: ERROR: <core> [pt.c:479]: fork_tcp_process(): init_child failed for process 20, pid 4162, "tcp receiver (generic) child=3"
Nov 3 09:00:55 Kamailio /usr/local/sbin/kamailio[4162]: ERROR: <core> [tcp_main.c:4868]: tcp_init_children(): fork failed: Success

Aside Note:

I'm using Kamailio v4.2 on centos and this issue appears whenever i replace the default config file with this config file from that link
http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb i want to use this file in particular because it is easy to me as beginner with Kamailo to configure it with Asterisk integration...thanks in advance everyone

the warning messages can be ignored -- perhaps we should make them notice or info, rather than warnings.

For address already in use, see if there is another application listening on that socket, can be a sip phone or even another kamailio running -- you can use netstat to check:

netstat -altpn

check UDP Listener parameter -u as well ... like:

netstat -anupn

Parameter:
-t = TCP
-u = UDP

Regards
Rainer
Cheers,
Daniel
